Description

Technical Field

[0001] This invention relates to the field of automatic packaging technology, and in particular to a labeling device. Background Technology

[0002] A carton labeling machine is a device specifically designed to affix labels to the surface of cardboard boxes, primarily used in logistics, warehousing, and production lines. These labels typically contain product information, barcodes, shipping instructions, and other details, facilitating subsequent management and tracking. In the context of the rapid development of e-commerce, carton labeling machines are playing an increasingly important role.

[0003] Currently, labeling of cartons mostly requires manual labeling by production workers or human-machine collaborative labeling. This not only results in a low labeling pass rate but also low labeling efficiency. As a result, automated labeling machines have been developed. However, in existing labeling machines, after picking up the label paper from the feed tape, a servo motor is required to keep the labeling mechanism away from the waste tape to avoid interference between the waste tape and the labeling mechanism. This setup requires a control system to control the positioning accuracy of the labeling mechanism, which not only increases the space occupied by the overall device but also makes it prone to failure and consumes more energy during use, thus increasing production costs. Summary of the Invention

[0004] To address the shortcomings of the prior art, the present invention provides a labeling device that eliminates the need for an additional control system to control the positioning accuracy of the suction cup assembly, making the structure simpler and more reliable while also reducing the overall space occupied by the device.

[0005] The technical effects to be achieved by this invention are realized through the following technical solutions:

[0006] This invention provides a labeling device, comprising:

[0007] Fixed base, including label feeding station and labeling station;

[0008] A label conveying mechanism is located at the label delivery station;

[0009] A label-grabbing mechanism, located downstream of the label-conveying mechanism, includes a transfer component and a suction cup component. The transfer component drives the suction cup component to slide along a first direction between the label-feeding station and the label-applying station. The suction cup component is slidably connected to the transfer component along a second direction perpendicular to the first direction.

[0010] A guide plate is disposed along the moving path of the suction cup assembly in a first direction, and the suction cup assembly continuously abuts against the guide plate;

[0011] The guide plate includes a first guide surface and a second guide surface connected in sequence. The distance between the second guide surface and the label feeding station in the second direction is greater than the distance between the first guide surface and the label feeding station in the second direction. When the suction cup assembly is located at the label feeding station, it abuts against the first guide surface. When the suction cup assembly is located at the labeling station, it abuts against the second guide surface to avoid the label conveying mechanism.

[0012] In some implementations, the guide plate further includes a third guide surface, the second guide surface being parallel to the first guide surface, and the third guide surface being connected to both the first guide surface and the second guide surface.

[0013] In some implementations, the label-collecting mechanism further includes a first elastic element disposed along a second direction, with its two ends connected to the transfer component and the suction cup component, respectively, and the suction cup component continuously abutting against the guide plate through the first elastic element.

[0014] In this implementation, the first end of the first elastic member is connected to the transfer component, and the second end is connected to the suction cup component, so that the suction cup component continuously abuts against the guide plate under the action of the force of the first elastic member.

[0015] In some implementations, the suction cup assembly includes a label-absorbing plate and a guide wheel. The label-absorbing plate is slidably connected to the transfer assembly. The label-absorbing plate is provided with a mounting portion. The guide wheel is rotatably connected to the mounting portion and abuts against the guide plate. The end of the first elastic member is connected to the mounting portion.

[0016] In this implementation, the guide wheel is rotatably connected to the mounting part. Under the action of the first elastic member, the label suction plate slides along the second direction away from the label conveying mechanism, thereby causing the guide wheel to abut against the guide plate.

[0017] In some implementations, the number of the first elastic elements is not less than two, and the two first elastic elements are spaced apart.

[0018] In some implementations, the label-collecting mechanism further includes a slider and a slide rail, the slider being connected to the transfer assembly, and the slide rail being connected to the label-collecting plate and located between the two first elastic members, the slide rail being slidably connected to the slider; and / or

[0019] The slider is connected to the label-absorbing plate and located between the two first elastic members, the slide rail is connected to the transfer assembly, and the slider is slidably connected to the slide rail.

[0020] In some implementations, the suction cup assembly further includes an elastic abutment, the suction plate has a suction hole, the elastic abutment is connected to the side of the suction plate away from the transfer assembly, and has a connecting hole communicating with the suction hole.

[0021] In this implementation, the elastic abutment is located between the label suction plate and the label paper. The elastic abutment acts as a buffer, allowing the label suction plate to more firmly stick the label paper to the object being pasted when pasting the label paper.

[0022] In some implementations, the transfer assembly includes a transfer seat, a guide post, a connecting plate, and a transfer drive. The transfer seat is slidably connected to the fixed seat. The first end of the guide post is connected to the transfer seat. The connecting plate is connected to the second end of the guide post. The suction cup assembly is connected to the side of the connecting plate opposite to the guide post. The transfer drive drives the transfer seat to move.

[0023] In some implementations, the transfer assembly further includes a second elastic element, which is sleeved on the guide post and has its two ends abutting against the transfer seat and the connecting plate, respectively.

[0024] In some implementations, the label conveying mechanism further includes an unwinding assembly, a peeling sheet, and a winding assembly, with the unwinding assembly located upstream of the peeling sheet and the winding assembly located downstream of the peeling sheet.

[0025] In this implementation, the peeling piece is positioned at the connection between the first guide surface and the third guide surface, so that after the suction cup assembly picks up the label paper, it abuts against the second guide surface through the third guide surface, thereby avoiding the label conveying mechanism.

[0026] In some implementations, the labeling device further includes an air blowing mechanism located at the end point of the travel of the suction cup assembly sliding in a first direction, with the air outlet of the air blowing mechanism facing the suction cup assembly.

[0027] In summary, the present invention has at least the following advantages:

[0028] The labeling device provided by this invention includes a transfer component that drives a suction cup component to slide along a first direction, a suction cup component that slides along a second direction and is connected to the transfer component, and a guide plate that is positioned along the first direction on the moving path of the suction cup component. The suction cup component continuously abuts against the guide plate and avoids the label conveying mechanism through the second guide surface of the guide plate. By setting a driving mechanism that cooperates with the guide plate, interference between the suction cup component and the label conveying mechanism can be avoided while the label is picked up and the labeling action is performed. Furthermore, there is no need to set up an additional control system to control the positioning accuracy of the suction cup component, making the structure simpler and more reliable while also reducing the space occupied by the overall device.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of the present invention.

[0041] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0042] Example 1:

[0043] Please see the appendix Figure 1 ~Appendix Figure 2 The labeling device of the present invention includes a fixed base 1, a label conveying mechanism 2, a label suction mechanism 3, and a guide plate 4.

[0044] Please see below. Figure 1 , Figure 1 The diagram illustrates the structural relationship between the fixing base 1, the label conveying mechanism 2, the label picking mechanism 3, and the guide plate 4 in an embodiment of the present invention. For ease of description, an example of the first and second directions is defined, specifically as follows: Figure 1 As shown, the XYZ coordinate axes are defined, where the first direction is parallel to the X-axis and the second direction is parallel to the Z-axis; these two directions are orthogonal to each other. It is understandable that the first and second directions may not be orthogonal.

[0045] Specifically, the fixed base 1 includes a label feeding station 11 and a label affixing station 12; the label conveying mechanism 2 is located at the label feeding station 11; the label suction mechanism 3 is located downstream of the label conveying mechanism 2, and the label suction mechanism 3 includes a transfer component 31 and a suction cup component 32. The transfer component 31 drives the suction cup component 32 to slide between the label feeding station 11 and the label affixing station 12 along a first direction, and the suction cup component 32 is slidably connected to the transfer component 31 along a second direction, which is perpendicular to the first direction; the guide plate 4 is located along the first direction on the moving path of the suction cup component 32, and the suction cup component 32 continuously abuts against the guide plate 4. The guide plate 4 includes a first guide surface 41 and a second guide surface 42 connected in sequence. The distance between the second guide surface 42 and the label feeding station 11 in the second direction is greater than the distance between the first guide surface 41 and the label feeding station 11 in the second direction. When the suction cup assembly 32 is located at the label feeding station 11, it abuts against the first guide surface 41. When the suction cup assembly 32 is located at the labeling station 12, it abuts against the second guide surface 42 to avoid the label conveying mechanism 2.

[0046] In this embodiment, the transfer component 31 is used to drive the suction cup component 32 to slide along the first direction. The suction cup component 32 can be slidably connected to the transfer component 31 along the second direction. The suction cup component 32 is used to pick up the label paper of the label conveying mechanism 2 and slides between the label feeding station 11 and the labeling station 12 under the drive of the transfer component 31, so that after the suction cup component 32 picks up the label paper in the label feeding station 11, it continues to slide to the labeling station 12, thereby enabling the suction cup component 32 to stick the label paper to the object to be labeled.

[0047] Specifically, the guide plate 4 is set along the moving path of the suction cup assembly 32 in the first direction. The first guide surface 41 of the guide plate 4 corresponds to the label feeding station 11, and the second guide surface 42 corresponds to the labeling station 12. The suction cup assembly 32 continuously abuts against the guide plate 4 during the process of picking up the label paper, feeding the label paper, and pasting the label paper. Since the distance between the second guide surface 42 and the label feeding station 11 in the second direction is greater than the distance between the first guide surface 41 and the label feeding station 11 in the second direction, the suction cup assembly 32 enters the labeling station 12 after picking up the label paper in the label feeding station 11. The suction cup assembly 32 abuts against the second guide surface 42, thereby avoiding the label conveying mechanism 2 and avoiding the problem of interference between the suction cup assembly 32 and the label conveying mechanism 2.

[0048] Understandably, the suction cup assembly 32 can be slidably connected to the transfer assembly 31 along the second direction. The side of the suction cup assembly 32 closest to the guide plate 4 continuously abuts against the guide plate 4. The distance between the second guide surface 42 and the label feeding station 11 in the second direction is greater than the distance between the first guide surface 41 and the label feeding station 11 in the second direction, that is, the second guide surface 42 and the first guide surface 41 are not on the same horizontal plane. The transfer assembly 31 drives the suction cup assembly 32 to slide between the label feeding station 11 and the labeling station 12. When the suction cup assembly 32 moves to the labeling station 12, the suction cup assembly 32 slides relative to the transfer assembly 31 along the second direction, so that the suction cup assembly 32 abuts against the second guide surface 42, thereby... After avoiding the label conveying mechanism 2 and labeling the object to be labeled, the transfer component 31 continues to drive the suction cup component 32 to move along the first direction. As the suction cup component 32 moves from the labeling station 12 to the label feeding station 11, it slides relative to the transfer component 31 along the second direction, so that the suction cup component 32 abuts against the first guide surface 41. The transfer component 31 continues to drive the suction cup component 32 to slide, thereby picking up the label and applying it. This cycle is repeated. The label picking and labeling action can be completed through a single drive mechanism, while avoiding interference between the suction cup component 32 and the label conveying mechanism 2. Compared with the prior art, the overall structure is simpler and more reliable.

[0049] In the aforementioned labeling device, the transfer component 31 drives the suction cup component 32 to slide along a first direction. The suction cup component 32 is slidably connected to the transfer component 31 along a second direction. The guide plate 4 is disposed along the moving path of the suction cup component 32 along the first direction. The suction cup component 32 continuously abuts against the guide plate 4 and avoids the label conveying mechanism 2 through the second guide surface 42 of the guide plate 4. By setting a driving mechanism to cooperate with the guide plate 4, interference between the suction cup component 32 and the label conveying mechanism 2 can be avoided while completing the label picking and labeling action. Furthermore, there is no need to set an additional control system to control the positioning accuracy of the suction cup component 32, making the structure simpler and more reliable while also reducing the space occupied by the overall device.

[0050] In some preferred embodiments, please refer to Figure 2 , Figure 2 The diagram illustrates the structural relationship between the first guide surface 41, the second guide surface 42, and the third guide surface 43 in an embodiment of the present invention. The guide plate 4 further includes a third guide surface 43. The second guide surface 42 is parallel to the first guide surface 41, and the third guide surface 43 is connected to both the first guide surface 41 and the second guide surface 42. The first guide surface 41 and the second guide surface 42 are arranged parallel to each other, and the third guide surface 43 is inclined between the first guide surface 41 and the second guide surface 42, so that the suction cup assembly 32 can smoothly move from abutting against the first guide surface 41 to abutting against the second guide surface 42, thereby ensuring the reliability of the guide plate 4.

[0051] Example 2:

[0052] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the labeling device of the present invention. Please refer to the appendix. Figure 2 ~Appendix Figure 4 .

[0053] Please see below. Figure 2 , Figure 2 The diagram illustrates the structural relationship between the first elastic element 33, the transfer component 31, and the suction cup component 32 in an embodiment of the present invention. The label suction mechanism 3 further includes a first elastic element 33 disposed along a second direction. The two ends of the first elastic element 33 are respectively connected to the transfer component 31 and the suction cup component 32. The suction cup component 32 continuously abuts against the guide plate 4 through the first elastic element 33.

[0054] In this embodiment, the first end of the first elastic member 33 is connected to the transfer assembly 31, and the second end is connected to the suction cup assembly 32, so that the suction cup assembly 32 continuously abuts against the guide plate 4 under the force of the first elastic member 33. Specifically, when the suction cup assembly 32 slides from the first guide surface 41 into the second guide surface 42, the suction cup assembly 32 slides relative to the transfer assembly 31 along the second direction under the action of the first elastic member 33, thereby causing the suction cup assembly 32 to abut against the second guide surface 42; when the suction cup assembly 32 slides from the second guide surface 42 into the first guide surface 41, the suction cup assembly 32 slides relative to the transfer assembly 31 along the second direction under the action of the first elastic member 33, thereby causing the suction cup assembly 32 to abut against the first guide surface 41. Preferably, the first elastic member 33 can be a tension spring.

[0055] It should be noted that by using a tension spring as the power to make the suction cup assembly 32 slide in the second direction, compared with the prior art which requires an additional servo motor as a power source, the labeling device of the present invention does not require additional electric or pneumatic assistance. Furthermore, by combining the two cycles of the suction cup assembly 32 sliding in the first direction and sliding in the second direction into one action, the labeling efficiency is effectively improved.

[0056] Further, please see Figure 3 , Figure 3 The diagram illustrates the structural relationship between the stop block 324 and the transfer component 31 in this embodiment of the invention. The suction cup component 32 has a stop block 324 on the side away from the guide plate 4. The stop block 324 abuts against the transfer component 31, thereby limiting the sliding stroke of the suction cup component 32 when it slides under the action of the first elastic member 33. This prevents the suction cup component 32 from exiting the labeling station 12 when it detaches from the guide plate 4, ensuring the positional accuracy of the suction cup component 32, and thus ensuring that the suction cup component 32 can accurately pick up the label paper.

[0057] In some preferred embodiments, the suction cup assembly 32 includes a label-absorbing plate 321 and a guide wheel 322. The label-absorbing plate 321 is slidably connected to the transfer assembly 31, and a mounting portion 3211 is provided on the label-absorbing plate 321. The guide wheel 322 is rotatably connected to the mounting portion 3211 and abuts against the guide plate 4. The end of the first elastic member 33 is connected to the mounting portion 3211. The guide wheel 322 is rotatably connected to the mounting portion 3211, and under the force of the first elastic member 33, the label-absorbing plate 321 slides in a second direction away from the label conveying mechanism 2, thereby causing the guide wheel 322 to abut against the guide plate 4.

[0058] In some preferred embodiments, the number of first elastic elements 33 is not less than two, and the two first elastic elements 33 are arranged at intervals. The two first elastic elements 33 are disposed opposite to each other on the side of the transfer assembly 31 near the label suction plate 321, and are respectively connected to the two sides of the side of the label suction plate 321 near the transfer assembly 31, so that the label suction plate 321 slides more smoothly under the force of the first elastic elements 33, thereby ensuring the stability of the label suction plate 321 during sliding and making the overall structure more reliable.

[0059] In some preferred embodiments, the label-collecting mechanism 3 further includes a slider 34 and a slide rail 35. The slider 34 is connected to the transfer assembly 31, and the slide rail 35 is connected to the label-collecting plate 321 and located between two first elastic members 33, with the slide rail 35 slidably connected to the slider 34; and / or the slider 34 is connected to the label-collecting plate 321 and located between two first elastic members 33, the slide rail 35 is connected to the transfer assembly 31, and the slider 34 is slidably connected to the slide rail 35. The slider 34 is slidably connected to the slide rail 35 to make the label-collecting plate 321 slide more smoothly and stably relative to the transfer assembly 31, avoiding the label-collecting plate 321 from getting stuck during sliding, thus preventing interference with the label conveying mechanism 2.

[0060] In some preferred embodiments, the suction cup assembly 32 further includes an elastic abutment 323. The suction plate 321 has suction holes 3212. The elastic abutment 323 is connected to the side of the suction plate 321 facing away from the transfer assembly 31 and has a connecting hole 3231 communicating with the suction holes 3212. The elastic abutment 323 is located between the suction plate 321 and the label paper, and acts as a buffer, allowing the suction plate 321 to more firmly adhere the label paper to the object being labeled.

[0061] In some preferred embodiments, please refer to Figure 4 , Figure 4 The diagram illustrates the structural relationship of the transfer seat 311, guide post 312, connecting plate 313, and transfer drive 314 in an embodiment of the present invention. The transfer assembly 31 includes the transfer seat 311, guide post 312, connecting plate 313, and transfer drive 314. The transfer seat 311 is slidably connected to the fixed base 1. The first end of the guide post 312 is connected to the transfer seat 311, and the connecting plate 313 is connected to the second end of the guide post 312. A suction cup assembly 32 is connected to the side of the connecting plate 313 facing away from the guide post 312. The transfer drive 314 drives the transfer seat 311 to move. The guide post 312 is connected to both the transfer seat 311 and the connecting plate 313. The transfer drive 314 drives the transfer seat 311 to slide along the fixed base 1, thereby causing the connecting plate 313 to slide along a first direction, which in turn causes the suction cup assembly 32 to slide along the first direction, ensuring the reliability of the overall structure.

[0062] In some more preferred embodiments, the transfer assembly 31 further includes a second elastic element 315, which is sleeved on the guide post 312 and has its two ends abutting against the transfer seat 311 and the connecting plate 313, respectively. The second elastic element 315 acts as a deceleration buffer, thereby preventing the suction cup assembly 32 from crushing the object being labeled when applying the label.

[0063] Example 3:

[0064] The difference between this embodiment and Embodiment 2 is that this embodiment further optimizes the structure of the labeling device of the present invention. Please refer to the appendix. Figure 5 .

[0065] The label conveying mechanism 2 also includes an unwinding assembly 21, a peeling sheet 22, and a winding assembly 23. The unwinding assembly 21 is located upstream of the peeling sheet 22, and the winding assembly 23 is located downstream of the peeling sheet 22.

[0066] In this embodiment, the unwinding assembly 21 is used to release the material tape, the winding assembly 23 is used to collect the waste material tape, and the peeling strip 22 is used to peel the label paper from the material tape. The peeling strip 22 is set at the connection between the first guide surface 41 and the third guide surface 43, so that after the suction cup assembly 32 picks up the label paper, it abuts against the second guide surface 42 through the third guide surface 43, thereby avoiding the label conveying mechanism 2.

[0067] In some preferred embodiments, the labeling device further includes an air blowing mechanism 5, which is located at the end point of the travel of the suction cup assembly 32 sliding in the first direction, with the air outlet of the air blowing mechanism 5 facing the suction cup assembly 32. The air blowing mechanism 5 is used to flatten the label paper, preventing the freshly peeled label paper from bending and causing the suction cup assembly 32 to fail to hold it. Preferably, the air blowing mechanism 5 can be a fan.

[0068] In the labeling device of the present invention, the transfer component 31 drives the suction cup component 32 to slide along a first direction, the suction cup component 32 is slidably connected to the transfer component 31 along a second direction, and the guide plate 4 is disposed on the moving path of the suction cup component 32 along the first direction. The suction cup component 32 continuously abuts against the guide plate 4 and avoids the label conveying mechanism 2 through the second guide surface 42 of the guide plate 4. By setting a driving mechanism to cooperate with the guide plate 4, interference between the suction cup component 32 and the label conveying mechanism 2 can be avoided while the label picking and labeling action is performed. Furthermore, there is no need to set an additional control system to control the positioning accuracy of the suction cup component 32, making the structure simpler and more reliable while reducing the space occupied by the overall device.

[0069] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0070] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.
